Whats holding me back?

phoeneous · 12-February-05, 10:05 PM

I cant get over 220x10. If I try 221x10 or 220x10.5, XP doesnt load.

Specs:

Abit NF7-S 2.0 (flashed BIOS to d10 Mantaray XT)
2500+ (unlocked)
2x512 Corsair XMS 3200
PowMax Demon 480w

Voltages:

VCCore= 1.75
VDimm= 2.8
Chipset= 1.7
AGP= 1.6

Suggestions?

$SOLID$ Necro · 12-February-05, 10:48 PM

Try the 9x multiplier and see if that helps.

What are your memory timings?

Try CAS 2.5-4-4-11

Have you tried any higher on the voltages?

You may have hit the limits of the CPU,Motherboard or Memory.

A single stick of memory can usualy get a higher FSB for testing purposes (One of the sticks may be holding you back)

I agree with Solid drop your multiplier, loosen your memory timings, and increase your voltage.How bout your temps are they still reasonable?
Solid congrats on your 3000th post

Looks like 240 is my limit. I hit 56'c on my ghetto "extremecooling" setup so I decided to back everything down. Ill be fine at 220. It was my timings, I bumped CAS from 2 to 2.5 and it went up, up, up. Good enough for me until I get a WC setup.

Thank you, I didn't even notice it until this morning!

Phoeneous, that seems like alot of voltage (1.9v) to the CPU for only 2.3GHZ

On my Mobile 2500+ I can hit 2.6GHZ with that much juice! (I know it's a lower voltage CPU, but still!)

You will get better performance at say 240x9, than you will 220x10 BTW

Do some benchmark testing and see for yourself

(Sandra, 3DMARK, AMD N-Bench, Aquamark, etc..)

Oh..and I prefer not to use half multiplier if I can avoid them (long story)

MaTtsPc · 13-February-05, 01:25 PM

Voltage is to high for the Vcore.. Dont know what kinda ram you got but the timmings still arent right anyways... loosing them up a lil. And your temp is WAY to high to laugh about! Get beter cooling and try again. And drop the Multi down more too. Good luck man your on the right track atleast

Explain "loosen up your timings"

$SOLID$ Necro · 13-February-05, 01:48 PM

CAS 2-2-2-5 is as tight as memory will usually run.

CAS 3-4-4-8 is (Generally) about as loose as you want to go, beyond that performance realy sux.

BTW, for some reason NForce 2 motherboard likes the last number to be 11, it just performs better for some reason.

You can try 2.5-4-4-11 or 3-4-4-11 and see if that helps

Make sure you bench test to find the sweet spot, each system has one

phoeneous · 13-February-05, 05:11 PM

You know that this an NF2 board right? Thats why I have my timings at 2-3-3-11. Isnt a higher T-ras generally better as it leaves the bandwidth "window" open for memory? So how could a T-ras of 7 possibly be better than a T-ras of 10 or 11?

Quote:


	Row active delay The delay that results when two different rows in a memory chip are addressed sequentially. Also known as T-ras. Values range from 1 to 15. Most NF7 users report better memory performance with a value of 11 or 10. Setting this value too low can result in data corruption. A good way to think of this setting is the time a page in a book is available to be read, before the book is closed and opened to a new page. If the book is closed before the page is fully read, you have to reopen the book to the same page to read it again, which means you wasted time progressing to the next page. However if you are done reading the page, leaving the book open too long also slows your progress to the next page. RAS-to-CAS delay The number of clock cycles that elapse between the row address being determined and the column address being sent out. Also known as T-rcd. Values range from 1 to 7. In most cases its best to leave this setting to the factory spec of your ram. Decreasing this value to 2 will improve performance at the risk of instability. Row-Precharge delay The number of clock cycles needed to precharge the circuits in order that the row address can be determined. Also known as T-rp. Values range from 1 to 7. In most cases, like for T-rcd, it is best to leave this setting at your factory ram specs. Decreasing it to 2 will also improve your performance at the risk of instability. Cas Latency Time The number of clock cycles that elapse from the column being addressed to the data arriving in the output register. Also known as T-cl. Values are 2.0, 2.5, 3.0. Setting this value lower will give the greatest memory improvement tweak. If the system becomes unstable, youll have to increase the value.

You already have an OCing guru helping you out here, but a PowMax PSU seems like it could be part of the problem to me.

That just could be one of his problems! Good one GF...

Thats why I asked. One forums says one thing and this forum says another. Shouldnt something as important as mem timings be a universal concept?

$SOLID$ Necro · 14-February-05, 02:00 PM

NF-2 benches best in most situations with 11

NF-3-250 seems to like 10

NF-4 seems to like 6-8, with 7 being the medium number

Here is one of the many results that I've looked at, some of my own testing has shown each combo responds differently, so try them yourself..it's just a general guideline that works for most situations.

EDIT:GF, it's ok to argue with a "Guru" a good one will explain his reasons...and sometimes, you can teach em' sumthin new by doing so...theories are constantly being revised

Just don't piss em off when your doing it though...LOL

Wasn't arguing with ya, just pointing out something you "may" have missed.

Not at all, I just thought $SOLID$ Necro left out the fact that your PSU may be in question also, nothing to do with you.
